Aspen Bibliography
Ungulate browsing represents a contemporary issue for forest development, influencing forest regeneration, composition, and management practices across the world, especially in North America. This review synthesizes findings from 101 studies conducted between 1980 and 2025 to examine patterns of herbivory damage through browsing by moose, elk, white-tailed deer, black-tailed deer, and bison. Despite regional variation, high ungulate density consistently emerges as the primary factor driving browsing intensity and ecological and economic impact, leading to decreased social acceptance of coexistence with ungulates. This review highlights the selective suppression of palatable species such as balsam fir, red oak, and white cedar, leading …

Plants, traditionally viewed as passive organisms, exhibit sensory and adaptive abilities that challenge conventional notions of plant biology. All organisms evolve ways to sense and interact with their surroundings, and plants, although lacking eyes, ears, or brains, perceive the world in sophisticated ways. Despite lacking a nervous system and other features typically associated with animals, plants can see, smell, hear, feel, learn, remember, and act similarly to animals. This review examines how plants perceive and respond to their environment using mechanisms analogous to vision, hearing, smell, taste, and touch, adjusting their morphology, physiology, and phenotype accordingly. Drawing from plant physiology, …

Polyhydroxyalkanoate (PHA) aliphatic polymers however efficiently biodegradable, still pose a contradiction with the principles of green chemistry. Use of bacterial strains capable of degrading synthetic plastics for the production of biopolymers i.e., PHAs may aid in reduction of plastic pollution. Bacterial strains PWA; Bacillus subtilis (MH142143), PWF; Bacillus tequilensis (MH142145), and PWG; Bacillus safensis (MH142146) were grown on waste shredded PET and PET flakes. Highest bioconversion of PET to PHA was observed using PET flakes. Strain PWF produced 40.47 % (0.815 g/L) and 31.80 % (0.626 g/L) PHA using PET flakes and shredded PET at 48 h, respectively. Whereas highest …

Understanding the interactions between plant-host-parasitoid plays a major role in insect pest management. Farmers in the southeastern United States rely on pasture systems for cattle milk and beef production, but the benefits of parasitoids and predators on major lepidopteran pests on pasture lands are still overlooked. Here, we aimed to identify and quantify the effect of parasitism on the true armyworm Mythimna unipuncta (Haworth, 1809) (Lepidoptera: Noctuidae) attacking teff grass Eragrostis tef (Zucc.) Trotter (Poaceae) and crabgrass Digitaria sanguinalis (L.) Scop. (Poaceae) in western Kentucky. In early August of 2023, 547 larvae of M. unipuncta were collected from experimental …

Political Agroecology In Syracuse: Local Understandings, Possibilities, And Barriers To Food System Transformation, Cooper Olds
Theses - ALL
In recent years, agroecology has begun to receive increasing attention from international institutions such as the United Nations Food and Agriculture Organization (UN FAO). For some, this is seen as a valuable case of up-scaling agroecology which will lead to greater institutional support for the framework. However, critical agroecologists have raised concerns that such institutional adoption is rather a form of co-optation where the social and political elements of agroecology are omitted to facilitate the integration of the framework into a wider program of food system reform. As a result, there is ongoing contestation over the framework between these co-opted …

The Northern California Current (NCC) system is a productive coastal ecosystem with a mosaic of temporal and spatial features. The phytoplankton community plays a crucial role in supporting the rich ecosystem and economically important fisheries of the NCC. Our study integrates data across two years (2022-2023) and multiple transects to investigate the community composition of two major phytoplankton groups in the NCC: picocyanobacteria and photosynthetic picoeukaryotes (PPE). The abundances and cell sizes of the phytoplankton were measured using flow cytometry. We found PPE present at similar concentrations in both summer and winter, while picocyanobacteria were much more abundant in the …

IGC Proceedings (1977-2023)
Optimisation of animal production per unit area results in a penalty to individual animal production and herbage intake. The objective of the present study was to examine the dynamic changes in a grass sward in relation to declining production and herbage intake in five day paddocks grazed by dairy cows. The study formed part of a larger project to examine the effects of stocking rate and grazing method upon milk production and herbage intake that is reported by Peyraud et al. (1989).

In the central part of Honshu island in Japan, seasonal variation of herbage mass is also large (Okajima et al., 1985). So, when the grazing managements, i.e. stocking rate, grazing intensity etc., were not appropriate, part of herbage produced was lost through standing dead and litter, or grazing cattle lose their body weight. Sward characteristics affect the grazing behaviour of cattle (Jamieson and Hodgson, 1979), and then affect the herbage production and utilization. Relative herbage intake of cows was related to sward height (Baker et al., 1981). So, sward height was used as the indicator of the grazing management in …

IGC Proceedings (1977-2023)
In conditions of pasture feeding sward selection and consumption by grazing animals is strongly influenced by characters of herbage (Forbes, 1986). Quantitative and qualitative state of the sward affects its consumption primarily through changes of such elements in animal behaviour as grazing time and number and size of bites (Hodgson, 1982, 1985). Relativelyt much research has been done to investigate the response to the grazed sward of such ruminants as sheep, while the response of cattle, and particularly of dairy cows, has received much less attention (Arnold, 1981 ; Holmes, 1980). This paper presents results of investigations on the effect …

Effect Of Grazing On Pasture Production In South-West Western Australia, K.M S. Curtis, A C. Dunlop, T O. Albertson
IGC Proceedings (1977-2023)
INTRODUCTION With a mediterranean climate in the south-west of Western Australia, pastures are composed of annual species from the genera Trifolium, Hordeum, Lolium, Bromus, Vulpia, Erodium and Artotheca. The length of the growing season ranges from 9 months near the coast to less than 5 months in the eastern wheatbelt. Seven million hectares of pastures are grazed predominantly by Merino sheep (about 33 millions). Stoking rate is the major factor affecting wool production on farm. An increase in stocking rate reduces wool production per sheep.Increasing the stocking rate reduces total pasture growth (Dunlop, et al., 1984) and changes the botanic …

Development Of A General Relationship Between Stocking Rate And Animal Production, J.M Van Heerden, N M. Tainton
IGC Proceedings (1977-2023)
One of the best known mathematical representations of the relationship between stocking rate and individual animal production, that of Mot (1960), postulated a modified exponential relationship. Subsequent workers, however, derived a linear relationship between stocking rate and production per animal unit, at least at stocking rates beyond a certain minimum value. One of these relationships, that of Jones & Sandland (1974), is widely used in South Africa. The results of grazing trials with sheep on complex grass/legume mixtures in the winter rainfall region of South Africa (van Heerden & Tainton, 1987-1988), however, suggested a degree of non-linearity in this relationship. …

Mixed Animal Species Grazing Under Temperate And Semi-Arid Conditions, T Nolan, J Connolly, L M. Guillon, C Sall, K Dieye, K Dieye, H Guerin
IGC Proceedings (1977-2023)
Mixed grazing has been practiced for a long time, under a variety of climatic conditions, combinations of animal species and grazing managements (Nolan and Connolly, 1977). They suggested that although mixed grazing research progress was impeded by difficulties associated with the increased number of variables involved it offered greater opportunity to improve resource use. The purpose of this paper is to present results from recent research carried out under temperate and semi-arid conditions related to individual animal and per unit area outputs, animal/vegetation relationships and complemetary patterns of grazing behavious in relation to more efficient and balanced use of vegetation …

Under the monsoon climate, maximum temperature showed 34 °C in August and minimum temperature showed - 15 °C in February, total rainfall amounting to 1.700 mm. Through the welfare of the grazing cattle, both hot, rain and frosty environment influence the animal production (Bennett et al., 1984; Done-Currie Jr et al., 1984; Fraser, 1983). In order to improve the welfare of grazing cattle under hot, cold, rain and attacks of the external parasites, the efficiency of cattle clothes were studied.

An annual gain of 1 ton cattle body weight per ha was attained in an intensively managed pasture (IMP) of the National Grassland research Institute, NGRI, in 1986. In this experiment the efficiency of solar energy converted into herbage and cattle body was not directly determined although seasonal changes in herbage and animal biomasses were measured. In current report, the energy budget for herbage and cattle body in this pasture was estimated and compared with that in an extensively managed pasture (EMP) using a system model.

Cattle Grazing Of Bahiagrass (Paspalum Notatum Flugge) Sward Canopy As Influenced By Dung Deposition, M Hirata, Y Sugimoto, M Ueno
IGC Proceedings (1977-2023)
It is commonly observed in a grazed pasture that the grazing animal rejects the herbage on and near the dung pat (Marsh and Campling, 1970). However, quantitative information on the dung-induced changes in herbage consumption is very limited. In this study, cattle grazing of the dung-deposited sward canopy is compared with that of the dung-free sward canopy in order to clear the cattle dung effect on the herbage consumption in a bahiagrass pasture.

Estimation Of Pasture Intake In Grazing Ewes, Using The Alkanes Of Plant Cuticular Waxes, H Dove, J Z. Foot, M Freer
IGC Proceedings (1977-2023)
Herbage intake in grazing animals is commonly estimated from faecal dry matter output, calculated from the dilution of orally-administered chromium sesquioxide (Cr203), and an in�� vitro estimate of herbage digestibility (e.g., Freer et al. 1988). A major disadvantage of this approach is that a single digestibility value is ultimately applied to all the animals in a group, despite the fact that both the level of intake of individual animals and the consumption of supplement can alter herbage digestibility (Waite et al. 1964). More recently, Mayes et al.(1986) obtained accrurate estimates of known herbage, from a combination of the faecal levels …

The aim of the programme of which this work is part is to investigate the role of mixed grazing in preservation of range vegetation and sustaining or improving animal production in the Senegalese Sahel. In this paper we apply the linear programming method of Connolly (1974) modified to allow for missing information, to data on animal preferences for plant species.

Intensive Continuous Dairy Cows Grazing Of An Heterogeneous Grassland: Botanical Evolution In Relation With The Animal Behavior, Anne Mathieu, B Leclerc, J L. Fiorelli, B Jeannin, B Hubert, E De Vaubernier
IGC Proceedings (1977-2023)
Intensive continuous grazing is now well established in temperate climate countries (Parker, 1987). In semi-continental climate, the adjustment of stocking rate to herbage growth is more complex (Mathieu and Jeannin, 1986). Moreover parcels are very often an assemblage of different types of permanent meadows. The question of animal behaviour in relation to this spatial heterogeneity, and the subsequent evolution of the pasture was posed. The perenniality of this grazing system is dependent on the trend of this evolution. An experimentation was carried out in the northeastern France (Mirecourt, Vosges) by INRA, in order to analyse spatial choices made by dairy …

Human And Animal Impacts On Vegetation And Forage Plants In The Southern Guinea Savanna Of Nigeria, L C. Nwaigbo
IGC Proceedings (1977-2023)
Human beings and animals interact with their habitat. This interaction changes the structure of the organization of communities of plants. The region that has been changed for worst with tress being replaced by grasses as a result of burning is the Savanna region of Nigeria. Annual fire is a common occurence in Nigerian Savanna and this ecological factor has altered the original vegetation of these areas. Burning is usually undertaken for clearing land for cultivation and also for production of a flush of fresh palatable grass for grazing by the nomadic cattle herdsmen. Forage plants like Afzelia africana, Pterocarpus erinaceus …

Manipulating The Plastic Response Of White Clover Through Grazing, In A Cool, Temperate Climate In New Zealand, R.J M. Hay, G S. Baxter
IGC Proceedings (1977-2023)
In Southland, New Zealand, a wide range of grazing systems are practised, from continuous set-stocking to year round rotational grazing. A problem is the apparent decline in contribution of white clover (Trifolium repens L.) to total sward production in older pastures. Cereal and brassica crops, which depleted soil N, were traditionally sown each year and used to ensure that about 20 % of any farm consisted of clover-dominant two and three year old pastures. Carran (pers. comm.) suggests that all-grass-farming has removed the N-deficit incentive for clover growth. Farmlet trials at the Gore Regional Station, DSIR, have shown that …

Some Factors Causing Temporal And Spatial Variation In White Clover Performance In Grazed Swards, S A. Grant, C A. Marriott
IGC Proceedings (1977-2023)
Stolon burial as a result of earthworm activity and poaching is common on many soil types in autumn and winter. The covering of soil is thought to protect against frost and thus benefit winter survival. On heavy soils in wet conditions treading can result in stolon burial during the growing season (Grant et al., 1988). The extent to which burial at this time adversely affects clover is unknown. Urination by grazing animals deposits the equivalent of 300-600 kg N/ha locally on the sward. Since the addition of fertiliser N to mixed grass-clover swards favours grass at the expense of clover, …
The Growth Of White Clover (Trifolium Repens L.) In Field Swards In Wales. A Review., D Wilman
The Growth Of White Clover (Trifolium Repens L.) In Field Swards In Wales. A Review., D Wilman
IGC Proceedings (1977-2023)
The purpose of the paper is to review some studies of white clover (Trifolium repens L.) growth in field swards in Wales, which were supervised by the author in the period 1976-88. White clover is a valuable species, from the point of view of both nitrogen fixation and animal nutrition, but it is used successfully on only a small proportion of farms in the United Kingdom. Studies such as those reviewed should contribute to greater success in white clover use.

Effects Of Sheep Grazing On Dry Matter Production And Persistence Of A Lucerne Crop, I Delgado Enguita
IGC Proceedings (1977-2023)
In Spain, lucerne is mainly grown on irrigated areas for hay production and dehydration industry. The utilization of lucerne under grazing is very infrequent, due to the detrimental effects on both, animal health and plants persistence that have been attributed to it. However, lucerne dry matter (DM) production and quality in addition of being its cultivation more economical than grasses, offer interesting advantages to be used as a green forage (Delgado, 1984). New Zealand workers (Agronomy Society of New Zealand, 1982) have stressed that lucerne could be successfully managed under grazing when long resting periods were provided between short grazing …

Rhizoma perennial peanut ( Arachis glabrata Benth.) is a forage legume species adapted to the well-drained soils of subtropical United States (Prine et al., 1981). Management studies with perennial peanut have concentrated on hay production and animal performance based on pure stands (Prine, 1981 ; Sollenberger et al., 1987). Mixtures of perennial peanuts and various tropical grasses have performed well in small plot studies, but the interrelationship of grass and perennial peanuts under grazing and the consequence this relationship has on stand productivity and animal performance has not been investigated. The summer grazing phase of a backgrounding systems trial, which …

IGC Proceedings (1977-2023)
Herbage intake, digestibility and leafiness or bulk density are well known as the main factors affecting the performance of grazing animals. But even in case where these factors are not so different, daily gain still varies among seasons or individuals (Blaser et al., 1981). In order to solve these problems by modeling approach (Okubo & Jacquard, 1985), seasonal changes in plant production, daily gain of cattle live-weight and seasonal variations in solar energy conversion into cattle gain were measured, and the importance (Okubo et al., 1985) of gross efficiency of digestible energy to net energy was discussed.

IGC Proceedings (1977-2023)
Great quantities of crop residues are produced in Brazil at harvest time. The production of rice straw reachs approximately ten million of tons each year and very small quantity is used for animal feeding. The interest on utilization of rice straw increased in the last years mainly due to possibility of ammonia use for improvement of nutritive value of crop residues (Sundstol el al., 1978 ; Saenger el al., 1983 ; Herrera-Saldana el al., 1982; Streeter and Horn, 1984; Grotheer el al., 1986; Horton and Steacy, 1979). The objective of this study was to measure the effect to ammoniation on …

Increasing The Contribution Of Grass Silage For Milk Production, C Thomas, A Reeve
Increasing The Contribution Of Grass Silage For Milk Production, C Thomas, A Reeve
IGC Proceedings (1977-2023)
The conservation of grass as silage rather than hay has become increasingly popular in Northern Europe. The increase in silage making has been associated with the increased intensification of animal production and improvements in our knowledge of the fermentation process. Despite the ability to produce grass silages with consistently high metabolisable energy (ME) and crude protein (CP) contents it has been calculated that on UK dairy farms silage barely meets the maintenance requirement of the cow (Phipps, 1986). The objective of the work reported here is to devise methods to increase the contribution of silage in the diet of the …

Chemical And Nutritive Values Of Three Ensiled Residues (Broad Beans, Peas And Soybean) In Comparison With Yellow Lupin Silage, J Efe Serrano
IGC Proceedings (1977-2023)
The agro-industrial residues of legumes in Portugal has increased recently in animal feeding, but with little information about the nutritive values of these diets. The few values from literature (Economides and Hadjidemetriou, 1974; Boza and Guerreiro, 1981 ; Escandon et al., 1983) or in Tables of Food Composition are quite different. In south of Portugal, the yellow lupin is an expanding forage used in sheep diets as hay or silage. The purpose of this work, and others in progress, was to compare the feeding value of silages made from three important residues with the yellow lupin silage.
